CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. patent application Ser. No. 13/506,587, filed Apr. 30, 2012.

This invention relates to a utility holding device and more particularly to a utility holding device, which greatly simplifies transport of tools and materials to work area and additionally is very suitable for use by an electrician or a plumber.

BACKGROUND OF THE INVENTION

Work on any building is inherently dangerous for any worker. For an electrician or plumber, there is a wide variety of tools and materials that the electrician or plumber must move to a work area before the electrician or plumber can start, do or complete the desired work. To simplify such movement, it is very desirable to have a carrying or holding device, or other apparatus capable of carrying such tools and materials to desired work area.

Due to the wide variety of tools and materials required for an electrician or plumber to use, it is difficult to design an appropriate device to accomplish this goal. With the change in materials and design tools, a device, which works for one set of material or tools, may not work for other sets of tools and materials. Thus, it becomes quite difficult to design an appropriate cart for an electrician or a plumber to use. If the cart is large enough to carry a substantial number of tools and materials, it is too bulky to use around the construction site. If it is small enough to be easily moved around a construction site, the cart may not be able to handle all of the desired tools and materials for a particular project.

Adjustability is another desired feature for such a utility holding device. For example, if the height of the device can be easily changed, the device becomes more flexible and able to fit into more places. Absent this adjustability, the value of the utility holding device is greatly decreased.

It is also useful if the utility holding device can be used with a ladder. In this way, the worker can use a ladder while having material and tools conveniently available. Such convenience provides for both safety and efficiency for the worker, as well as the project itself.

Yet such a cart is a very desirable device. Not only is the work with such a utility holding device made more efficient, safety on the job and for the worker can be increased. This clearly means safety for both the workers and for the observers. Worker safety is improved by reducing material trips up and down the ladder, as well as for other reasons. Observer safety is obtained when less material leaves the work surface as well as for other reasons.

If this cart can cooperate with other implements at the construction site, even more advantages are obtained. For example, if this cart can be used with a ladder, whether the ladder includes a tray or not, great advantages are obtained. If the utility holding device can be used with a scaffold or a lift, further advantages are obtained.

Many times, an electrician or plumber is required to use a ladder. If the cart for transporting tools and materials cooperates with the ladder, great advantages are obtained. Not only does the worker become more efficient, safety is promoted. Therefore, a cart, especially a cart suitable for use by an electrician or a plumber, provides many desired results.

So improvements in ladder safety and worker safety can positively enhance working conditions for the workers, and others in and around the construction area. It is very desirable to create a device to accomplish these goals.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to several embodiments of the invention that are illustrated in accompanying drawings. Whenever possible, the same or similar reference numerals are used in the drawings and the description to refer to the same or like parts or steps. The drawings are in simplified form and are not to precise scale. For purposes of convenience and clarity only, directional terms such as top, bottom, left, right, up, over, above, below, beneath, rear, and front, may be used with respect to the drawings. These and similar to directional terms are not to be construed to limit the scope of the invention in any manner. The words attach, connect, couple, and similar terms with their inflectional morphemes do not necessarily denote direct or intermediate connections, but may also include connections through mediate elements or devices.

The utility holding device of this invention provides many great advantages, especially in the construction and plumbing industries. An especially successful version of this utility holding device is as a cart for an electrician or plumber to transport the required tools and materials around the construction site. The utility holding device has a base supporting a main storage area and a top segment. Telescoping or fixed arms connect the base to the top segment. A handle facilitates moving the top segment relative to the base. Observer safety is obtained when less material leaves the work surface of the top segment, because of the high work tray edges. The top segment is either a top compartment tray or an aperture tray.

The base is generally rectangular with a caster, preferably a lockable caster, mounted at each corner thereof. Thus, the utility holding device can be moved on the casters, with the casters being locked or unlocked as desired. Also, this utility holding device may be releasably secured to a desired surface. This surface may be ladder, a scaffold, or other suitable surface.

Referring now to FIG. 1 and FIG. 2, the utility holding device 100 has base 120 with top compartment tray 140 mounted thereon, with fixed risers 218. Top compartment tray 140 is the top segment in this embodiment. Thus, fixed risers 218 connect base 120 to top compartment tray 140. Lockable casters 170 support base 120 and are oppositely disposed from the top compartment tray 140. Lockable casters 170 allow the utility holding device 100 to be easily transported around the work area but securely positioned once a desired destination is reached. Operation of the top compartment tray 140 is supported by main storage area 130 and base 120.

While fixed risers 218 are depicted in FIG. 1 and FIG. 2, the telescopic assemblies 230 of FIG. 22, FIG. 23, and FIG. 24 may also be used to connect top compartment tray 140 to base 120. Handle 220 is centrally located in and facilitates moving top compartment tray 140 to different heights above main storage area 130 along the telescopic assemblies 230. Such adjustments make utility holding device 100 extremely useful.

Adding FIG. 3, FIG. 4, and FIG. 5 to the consideration, the structure of utility holding device 100 and its utility relative to metal ladder 102 becomes clearer. Metal ladder 102 includes ladder tray 104, which supports utility holding device 100 thereon. More specifically, base 120 of utility holding device 100 has an attachment means, which in the preferred embodiment is a ladder anchor plate 122. Ladder anchor plate 122 has an upper threaded aperture 124 and a lower threaded aperture 126. Ladder anchor plate 122 extends from base 120 and includes lower threaded aperture 126 to receive anchor bolt 106 in threaded relation therewith. Lower threaded aperture 126 allows for proper alignment between anchor bolt 106 and cross member 112 due to the position of ladder tray 104 on metal ladder 102. Ladder anchor plate 122 reaches above, behind, and under cross member 112 to secure the utility holding device 100 to metal ladder 102. Anchor bolt 106 may be placed into contact with cross member 112 to provide additional support between the utility holding device 100 and metal ladder 102. Utility holding device 100 does not need to contact the vertical members 110 of metal, ladder 102 for additional support.

Turning now to FIG. 6, metal ladder 102 includes ladder tray 104. To ladder tray 104, base 120 of utility holding device 100 (FIG. 1) is attached. Base 120 includes a ladder anchor plate 122. Base 120 rests on ladder tray 104. Ladder anchor plate 122 includes a lower threaded aperture 126. Through lower threaded aperture 126, anchor bolt 106 may be placed in a threaded relationship therewith and into contact with cross member 112 of the metal ladder 102. This procedure secures base 120 to cross member 112 and ultimately the utility holding device 100 to metal ladder 102.

Now adding FIG. 7, FIG. 8, and FIG. 9 to the consideration, the securing of utility holding device 100 to non-metallic ladder 108 is depicted. Ladder anchor plate 122 of utility holding device 100 fits over cross member 112 of non-metallic ladder 108. Then anchor bolt 106 can be placed in a threaded relationship with upper threaded aperture 124. Utility holding device 100 rests against and is further supported by the two vertical members 110 of non-metallic ladder 108. In this fashion, utility holding device 100 is secured to non-metallic ladder 108.

With the addition of FIG. 10, attaching and securing the utility holding device 100 (FIG. 7) to the non-metallic ladder 108 is accomplished through the ladder anchor plate 122 and the upper threaded aperture 124. Ladder anchor plate 122 attaches on above, behind, and under cross member 112. The anchor bolt 106 contacts the cross member 112 through the upper threaded aperture 124. Due to the position utility tray 100 takes on non-metallic ladder 108, upper threaded aperture 124 must be used so that anchor bolt 106 is able to contact cross member 112 and provide a secure connection.

When use of utility holding device 100 is considered with the power scaffold 200, one must consider FIG. 11, FIG. 12, FIG. 13, FIG. 14, FIG. 15, FIG. 16, FIG. 17, FIG. 18, and FIG. 19. It is possible to use adjustable anchor clamps 142 of top compartment tray 140 to support the utility holding device 100 on the power scaffold 200. More specifically, railing 202 of scaffold 200 and receives the adjustable anchor clamps 142.

To adjust the anchor clamps 142, a spring loaded latch pin 208 is used. The spring loaded latch pin 208 fits into latch pin washer 216 and then through female threaded aperture 128 in top compartment tray 140. Deployed aperture 210 or closed aperture 212 on adjustable anchor clamp 142 may align with the female threaded aperture 128. Rear clamp guide cradle 136 is situated below the top compartment tray 140 and has a cradle aperture 138 alignable with female threaded aperture 128 and deployed aperture 210 or closed aperture 212.

Each adjustable anchor clamp 142 has a fully extended position 204, a closed position 206, and a secured railing position 190. Fully extended position 204 requires no special aperture on adjustable anchor clamp 142 (FIG. 17, FIG. 18, and FIG. 19). Spring loaded latch pin 206 inserts into female threaded aperture 128 on top compartment tray 140. Fully extended position 204 allows the railing to be inserted or removed. Deployed aperture 210 and closed aperture 212 are positioned on adjustable anchor clamp 142 in order to provide for positioning thereof as desired.

Deployed aperture 210 provides for secured railing position 190 (FIG. 12, FIG. 13, and FIG. 19). Secured railing position 190 allows adjustable anchor clamp 142 to hold utility holding device 100 in a secure position on railing 202. Closed aperture 212 provides for closed position 206 (FIG. 15 and FIG. 16) of adjustable anchor clamp 142 locking it in place for safety and convenience when utility holding device 100 is not in use. Closed aperture 212 permits concealed end 214 of spring loaded latch pin 208 to be concealed in top compartment tray 140. Thus, the adjustable anchor clamps 142 provide for use of utility holding device 100 with the scaffold 200.

Inner side rail 132 and outer side rail 134 are attached to the bottom of top compartment tray 140. Inner side rail 132 and outer side rail 134 are parallel with a space between them to accommodate adjustable anchor clamp 142. Inner side rail 132 and outer side rail 134 serve as a guide to keep adjustable anchor clamp 142 in place horizontally as it slides between its various positions.

Front clamp guide cradle 146 and rear clamp guide cradle 136 are mounted perpendicularly to inner side rail 132 and outer side rail 134. Adjustable anchor clamp 142 is slidably mounted between inner side rail 132 and outer side rail 134 and underneath front clamp guide cradle 146 and rear clamp guide cradle 136. Front clamp guide cradle 146 and rear clamp guide cradle 136 support adjustable anchor clamp 142 and prevent it from falling downward.

Outer side rail 134 has outer rail aperture 152, rear clamp guide cradle 136 has rear cradle aperture 156, and top compartment tray 140 has top aperture 160, which cooperate to receive bolt 158 to form a secure connection between outer side rail 134, rear clamp guide cradle 136, and top compartment tray 140. Front clamp guide cradle 146 has front cradle aperture 154 which cooperates with outer rail aperture 152 and top aperture 160 to receive bolt 150 to secure outer side rail 134 and front clamp guide cradle 146 to top compartment tray 140. Inner side rail 132 has inner rail aperture 150 which cooperates with rear cradle aperture 156 and top aperture 160 to receive bolt 158 to secure inner side rail 132 and rear clamp guide cradle 136 to top compartment tray 140. Inner rail aperture 150 also cooperates with front cradle aperture 154 and top aperture 160 to receive bolt 158 to secure inner sider rail 132 and front clamp guide cradle 146 to top compartment tray 140.

Clamp jaw base 148 extends from an edge of utility holding device 100 and more particularly top compartment tray 140, and locks the railing in place with adjustable anchor clamp 142 in secured railing position 190. Adjustable anchor clamp 142 is guided by inner side rail 132 and outer side rail 134 and to prevent adjustable anchor clamp 142 from being removed too far, and thus out of inner side rail 132 and outer side rail 134, clamp slide stop 144 is positioned at the end of adjustable anchor clamp 142.

By comparing FIG. 20, FIG. 21, FIG. 22, and FIG. 23, it can be seen that utility holding device 100 has a great number of advantages for both the electrician and the plumber. Tools and working materials can be transported more easily and efficiently. Those tools and working materials can also be moved relative to a metal ladder 102, a non-metallic ladder 108, or a lift or scaffold 200 as desired.

Referring specifically to FIG. 22, telescopic assemblies 230 can be clearly seen. The telescopic assemblies 230 are usually four in number and appear at each corner of utility holding device 100. Thus a connection is provided between base 120 and top compartment tray 140.

Each telescopic assembly 230 has a base tube 232, a central tube 234, and an end tube 236. Base tube 232 joins base 120 to central tube 234. End tube 236 joins central tube 234 to top compartment tray 140. With the use of spring lock buttons 238, central tube 234 can be moved in and out of base tube 232, and end tube 236 can be moved in and out of central tube 234 and positioned relative to each other. By the same token utility holding device 100 can have top compartment tray 140 moved to a lowered position 248 (FIG. 21) relative to base 120. Also, utility holding device 100 can have top compartment tray 140 moved to raised position 228 relative to base 120 (FIG. 20).

In FIG. 23, a second embodiment of telescopic assemblies 230, flexible length risers 244, can be clearly seen. Flexible length risers 244 are generally four in number and are positioned at each corner of utility holding device 100. Flexible length risers 244 hold top compartment tray 140 in various positions relative to base 120. Such positions include lowered position 248 (FIG. 21) and raised position 228 (FIG. 20). Such flexibility adds greatly to the functionality of the utility holding device 100.

Flexible length risers 244 move in and out of fixed tube 246. Fixed tube 246 has a locking pin aperture 242 and flexible length riser 244 has a plurality of locking pin apertures 242. Flexible length riser 244 is moved into or out of fixed tube 246 to a desired position and a locking pin aperture 242 on each is aligned and secured with locking pin 240. This allows the top compartment tray 140 to be secured to the base 120 at a variety of positions.

Turning now to FIG. 24, the flexibility of utility holding device 100 can be clearly seen. Utility holding device 100 is securely connected to a desired surface 400. The surface 400 supports the utility holding device 100 as desired. Typical of the surface 400 is a ladder 296 (FIG. 34), such as a metal ladder 102, a non-metallic ladder 108, any other suitable ladder or scaffold or lift 200.

For example, base 120 of the utility holding device 100 can attach to surface 400. Base 120 can attach through the connection of ladder anchor plate 122, ladder tray 104, and cross member 112 (FIG. 3, FIG. 4, FIG. 5, and FIG. 6). Base 120 may also attach through the connection of ladder anchor plate 122 and cross member 112 (FIG. 7, FIG. 8, FIG. 9, and FIG. 10). Or, base 120 may connect to railing 202 of scaffold or lift 200 through adjustable anchor clamp 142 (FIG. 11, FIG. 12, FIG. 13, FIG. 14, FIG. 15, FIG. 16, FIG. 17, FIG. 18, and FIG. 19). Also, base 120 may attach to the surface 400 through any other suitable method or device.

Base 120 is attached to top compartment tray 140 through connecting device 121. Connecting device 121 may be flexible length risers 244 with locking pin 240 (FIG. 23), telescopic assemblies 230 with spring lock button 238 (FIG. 22), fixed risers 218 (FIG. 1), or any other suitable device to provide a secure and stable connection.

Taking FIG. 25 and FIG. 26 together, a tension gripper 250 is positioned on fluorescent light box holder 260, at a top portion thereof. Tension gripper 250 fastens to the lip 254 of top compartment tray 140. While a second tension gripper 250 is positioned on a bottom portion of the fluorescent light box holder 260 in order to latch onto base lip 254 of base 120. Into fluorescent light box holder 260 may fit a boxed supply of fluorescent bulbs 252.

Lip 254 also provides a retaining or safety function for any tools or other objects that may be placed in main storage area 130 or top compartment tray 140. Lip and base lip 254 provides a high retaining edge so that objects do not fall out of main storage area 130 or top compartment tray 140.

Now adding FIG. 27, FIG. 28, and FIG. 29 to the consideration, the combination shows the flexibility of electrical transportation by a utility holding device 100. To that end, a power strip 264 with the power cord 266 may be attached to the utility holding device 100. Tension gripper 250 supports the power strip 264 and cord or hose holder 270 thereon by attaching to lip 254 of top compartment tray 140. Power cord 266 is held in the cord or hose holder 270.

Also, cord or hose holder 270 is an optional but preferred embodiment. Cord or hose holder 270 has tension gripper 250 which attaches to lip 254 of top compartment tray 140. Cord or hose holder 270 provides convenient storage for power cord 266.

Now adding FIG. 30 and FIG. 31 to the consideration, the function of tool holder 280 becomes clear. Tool holder 280 contains tools 282 and attaches to lip 254 of top compartment tray 140 of utility holding device 100 with another tension gripper 250. Clearly tools 282 may be any required tools for the job at hand. Thus, utility holding device 100 allows great flexibility in providing easy access to tools 282.

Still another modification is available by considering FIG. 32 together with FIG. 33. A welding hose 284 connects welding tank 286 to welding torch 298 to welding nozzle 288. Welding tank 286 rests in base 120. Hose 284 rests in cord or hose holder 270. Nozzle 288 and torch 298 are held in position through torch cradle 290. Torch cradle 290 is held in place by tension gripper 250 which attaches to lip 254 of top compartment tray 140. More particularly, torch cradle 290 includes a nozzle rest 292 on one side of tension gripper 250 with handle holster 294 on the opposing side of tension gripper 250. Handle holster 294 accepts torch 298 and nozzle rest 292 accepts nozzle 288.

A first ladder carrying modification appears in FIG. 34, FIG. 35, FIG. 36, and FIG. 37. To that end a top-ladder holder 300 is secured to top compartment tray 140, while a bottom-ladder holder 310 is secured to base 120. Both top-ladder holder 300 and bottom-ladder holder 310 have a tension gripper 250 thereon which attaches to lip or base lip 254 of top compartment tray 140 or base 120. Oppositely disposed therefrom is a rung support 304 to receive cross member 112 of the ladder 296. Ladder 296 may be a metal ladder 102 (FIG. 3) or a non-metallic ladder 108 (FIG. 7). In this fashion, either ladder 296 is held vertically. This adds great flexibility to the utility holding device 100.

Referring specifically to FIG. 34 and FIG. 35, the base 120 includes a wheel extension 320 in a deployed position 322 (FIG. 34) and a stored position 324 (FIG. 35). Two of lockable casters 170 are mounted on either end of a wheel housing 326. A slide bar 328 is positioned on base 120 between the lockable casters 170. The slide bar 328 fits movably into support slot 330 on wheel housing 326. Slide bar 328 maintains the wheel housing 326 more securely inside base 120 when in stored position 324. When slide bar 328 permits deployed position 322, utility holding device 100 has a wider base and becomes more stable especially when accommodating the bulk and weight of ladder 296. When slide bar 328 permits stored position 324, utility holding device 100 has a narrower base and becomes more easily transportable.

To hold a ladder 296 in a horizontal position such as is shown in FIG. 38 and FIG. 39, a U-shaped ladder cradle 340 is used. Again, ladder 296 may be a metal ladder 102 (FIG. 3) or a non-metallic ladder 108 (FIG. 7). In this fashion, either ladder 296 is held horizontally.

Each U-shaped ladder cradle 340 has a tension gripper 250 to attach to lip 254 on opposing sides of top compartment tray 140. On each side of the U-shaped ladder cradle 340 are cradle apertures 342. As the ladder 296 fits into the U-shaped ladder cradle 340, a bungee cord 344 is put around the ladder 296 and inserted into the each of the cradle apertures 342. Thus, the ladder 296 is secured to the utility holding device 100. A locking lip 338 is positioned adjacent to tension gripper 250 to brace the U-shaped ladder cradle 340 against the top compartment tray 140.

Now adding FIG. 40, FIG. 41, FIG. 42, and FIG. 43 to the consideration, the structure and function of bucket embodiment 350 of utility holding device 100 can be clearly seen. In this embodiment, aperture tray 370 replaces top compartment tray 140 as the top segment.

As seen in FIG. 23, top compartment tray 140 may be connected to base 120 through the cooperation of locking pin 240 and locking pin apertures 242. To remove top compartment tray 140, locking pin 240 is released from the preferably four locking pin apertures 242. Then the preferably four flexible length risers 244 are pulled out of and removed from the corresponding fixed tubes 246.

Once top compartment tray 140 is removed, aperture tray 370 can be attached. The preferably four flexible length risers 244 of aperture tray 370 are inserted into the corresponding fixed tubes 246 in a male to female relationship. The flexible length risers 244 are inserted into the fixed tubes 246 until the aperture tray 370 is at the desired height relative to base 120. Then, the preferably four locking pin apertures 242 are aligned with the locking pin aperture 242 on fixed tubes 246 and the connection is secured with locking pin 240.

Aperture tray 370 has a bucket aperture 380 to receive a bucket 390. Bucket 390 sits in bucket aperture 380 and can be inserted or removed as desired. Bucket 390 may be filled with water or another liquid for cleaning or other purposes and the bucket 390 is removed to add fresh water or empty soiled water as needed. Bucket 390 can rest in aperture tray 370 and be transported around a site with base 120.

Bucket 390 has bucket handle 392 which is useful for attaching or removing bucket 390 into or from bucket aperture 380. Handle 392 also offers great convenience when transporting bucket 390 once it has been removed from aperture tray 370. Bucket handle 392, when bucket 390 is attached to aperture tray 370, can also be used to help maneuver utility holding device 100 around the site.

Aperture tray 370 also has tray handle 372. Tray handle 372 is depicted in upward position 374 in FIG. 40 and downward position 376 in FIG. 41. Upward position 374 allows tray handle 372 to be used to maneuver utility holding device 100 especially when bucket 390 is removed from aperture tray 370. Downward position 376 allows tray handle 372 to be conveniently stored when it is not in use especially when bucket 390 with bucket handle 392 is positioned in aperture tray 370.

This removable and flexible attachment provides great benefits for the utility holding tray 100. The interchangability between top compartment tray 140 and aperture tray 370 allows the user to match a top attachment for the desired purpose. Thus, utility holding device 100 has great flexibility and versatility.

Aperture tray 370 can be attached to base 120 in the manners previously described. Aperture tray 370 can have a series of fixed risers 218 (FIG. 1 and FIG. 2). Or, aperture tray 370 can use telescopic assemblies 230 and spring lock button 238 to connect to base 120 (See FIG. 22). Also, aperture tray 370 can have flexible length risers 244 and locking pin 240 to connect to base 120 (See FIG. 23).

Aperture tray 370 has lip 254 and base 120 has base lip 254. Tension gripper 250 can still be utilized to attach various components to utility holding device 100. Florescent light box holder 260 (See FIG. 25), power strip 264 (See FIG. 27 and FIG. 28), cord or hose holder 270 (See FIG. 27 and FIG. 29), tool holder 280 (See FIG. 30 and FIG. 31), torch cradle 290 (See FIG. 32 and FIG. 33), top-ladder holder 300 (See FIG. 34 and FIG. 36), bottom ladder holder 310 (see FIG. 34 and FIG. 37), and U-shaped ladder cradle 340 (See FIG. 38 and FIG. 39) can be attached to lip 254 of aperture tray and base lip 254 of base 120 in the previously described manner.

FIG. 42 depicts bucket embodiment 350 with the option of bucket 390 or insert 394. Bucket 390 may be removed and replaced with insert 394. Insert 394 is secured in place through the cooperation of female snap 384 and male snap 382. Insert 394 provides a flat surface to store tools 282 or other objects. In FIG. 43, insert 394 has partitions 396 and replaces bucket 390. Partitions 396 provide convenient storage for screws or other small objects. Also, insert 394 may have partitions 396 and apertures 388. Apertures 398 provide convenient storage for tools 282 such as screw drivers or pliers.

Cover 378 is a preferred option for the utility holding device 100 and can be used in any of the embodiments depicted in FIG. 1 through FIG. 43. Cover 378 attaches to ladder anchor plate 122 and is secured by friction. Cover 378 covers ladder anchor plate 122 and provides an aesthetic function.
